Mg 4 headlights failed to come on

[siteguru]

Surely you'd know if your headlights were off? The darker than expected piece of tarmac in front of you should be a huge clue.

That's not the case as you can not disable the daytime running lights and they turn off as well with the fault Also the mg4 dash is telling you that the headlights are on .

You wouldn't know if they're off in a well lit area like a town but what confuses even more the car is displaying your headlights are on . But they're not

At the beginning of this thread we discussed the possibility this is linked to the ‘welcome lights’ setting being switched on
Perhaps you can try disabling that and see if it somehow stops the problem from happening again.

Just in case it happens to me, when this fault occurs does flicking the switch to off then on, or off then auto, not bring the lights back on ?

Nope. Tried that with no luck. Stop, lock and restart sorted it.

As Rudi suggested below, it wasn’t really noticeable on a well lit road. As soon a I hit the M’way it became all too obvious. Again, it made it more confusing as the dash was saying all was working on auto.

I had the same issue today. when I unlocked the car, the headlight went on. When I started to drive, the headlight went off, although dash is showing headlight is on.

lock and unlock didn't help, press and hold the home button to reset the car, the light still didn't go on. but after 15 secs or so, the headlight turned on itself.

Has anyone found a solution to this?

Jesus, can mg just stop with the bad glitchy software. I had mine a year and the software still felt very much in Beta phase.

Do you have the ‘welcome lights’ option enabled? If yes, try disabling it and see whether it ever happens again.

Yes, I do. If it happens again, I will try to that. Thank you for the suggestion.

Exact same issue today. Oncoming traffic beeping! Resolved by exiting the car, locking, unlocking. Video of issue has been recorded (screenshot attached). Will discuss with MG4 dealership.

Why? How would this affect things?

Because bug

Oh. Thanks.

Hope that works now! Thanks for the workaround.

Have had this happen once in 21,000 kms. As others have said, car parked in daylight hrs. Walked back.to car at night, all seemed normal incl auto lights turning lights on at least on the dash. Short distance and noticed dark on the road. Pulled over and sure enough headlights off but dash showed they they were on. Tried turning lights on and off, etc, etc. I fixed by rebooting using home button long press. Default is welcome screen on. Never happened since so not that concerned.

Exactly the same just happened to me, luckily at twilight, but didn't know to do the turn off ( re-boot) and by the time I got home it was properly dark. Very scary. I then read this forum and went out and restarted the car after 10 mins parked and they worked fine. Shocking that this apparently "just happens".

Was there ever a fix for this? I've got a new MG4 Trophy (January 2025) and the headlights completely fail. Left the car alone for 10 minutes and came back - no luck, then left the car for an hour, everything back working again.

As previously state in others' threads, the dashboard says the lights are on, reality shows otherwise

 

[fnegroni]

i would hope latest updates have the required bug fix. For now there appears to be a workaround which is as mentioned above, to disable welcome lights (at least, since that was suggested, no one of those who changed the setting has reported the bug reoccurring)

This happened to me last night, driving back from London.
2023 MG4 SE with <7,000 miles.
Whatever the cause is, it has not been resolved properly, meaning the potential for a fatal accident still exists in these cars.

Has car been updated at service? I had it once and never since.
